SAN DIEGO (AP) — A San Diego police officer accidentally shot himself in the leg Sunday while pursuing a hit-and-run suspect who pointed a weapon at officers and was eventually arrested on the roof of a parking structure near the finish line of an annual marathon, authorities said.

Officers fired at the woman but missed after she brandished the weapon at the parking facility at the edge of a downtown plaza shared by City Hall, police Chief David Nisleit told reporters.

The suspect, who the police did not identify, threw the weapon from the top of the structure to the street below before being taken into custody, Nisleit said. It was unclear what type of weapon it was, but investigators were looking into whether it was a pellet gun that resembles the real thing, the chief said.

Detectives were also investigating whether the woman was connected to a kidnapping in nearby Chula Vista, Nisleit said. In that incident a man called police to report that he was bound and gagged at gunpoint but managed to escape, he said.

In announcing the woman’s arrest, police said the scene was secure and there was no threat to the area near the San Diego Rock ‘n’ Roll Marathon, which brought thousands of people downtown along with a heavy police presence. Organizers said there were 27,000 registered runners in the marathon and half-marathon.
